Double head sleeper structure

ABSTRACT

A double head sleeper structure mainly comprises a shoe body and two crossing shoestrings. The shoe body appears semicircular at both ends and a little concave in the middle of two sides. The size of shoe body varies to meet different user&#39;s need. The shoestring length is four fifth of the shoe body length. The two shoestrings cross with each other at the center of shoe surface of shoe body. The two ends of the shoestring attach the two opposite sides of shoe body at a position two third of the shoe body length from the shoe end. Such a design allows the user to put feet in shoes without need to watch for the shoe head direction. Particularly, when the feet are in shoes, the crossing point is forced to move a little forward, so the shoes look just like traditional design to cover the feet.

BACKGROUND OF THE INVENTION

1. Field of the Invention

Sleepers are a necessity for daily life and it provides convenience andcomfort. In recent years, living standard is significantly improved.

2. Description of the Related Art

Sleeper design tends to be versatile and improving. However, currentsleeper design limits the use to one direction, so users have to watchfor shoe head direction before wearing shoes. This certainly causes someinconvenience

SUMMARY OF THE INVENTION

To improve quality of life and increase convenience, the inventorimproved the current drawbacks for shoes and came up with a new shoedesign. It is a double head shoe structure. When wearing or removingshoes, the user does not need to pay attention to shoe head direction.This design brings in much convenience by saving time and labor.

DETAILED DESCRIPTION OF THE INVENTION

Please refer to FIG. 1. The double head shoe structure in the presentinvention mainly comprises a shoe body 1 and two crossing shoestrings 2.

The shoe body 1 appears semicircular at both ends and a little concavein the middle of two sides. The length of shoe body 1 varies in threelevels: large, medium and small to meet different user's need.

The shoestring 2 length is four fifth of the shoe body 1 length. The twoshoestrings 2 cross with each other at the center of the shoe surface 11of the shoe body 1. The two ends 21 of the shoestring 2 attach the twoopposite sides of shoe body 1 at a position two third of the shoe body 1length from the shoe end.

The attachment of the two ends 21 of the shoestring 2 is shown in FIG. 1and FIG. 2 and is a direct clamping in a slot 13 between the shoesurface 11 and the shoe bottom 13. Alternatively, the attachment asshown in FIG. 3 and FIG. 4 can be a direct placement into a through hole14 from shoe surface 11 to shoe bottom 12. The slot 13 (as position A inFIG. 2) or the through hole 14 (as position B in FIG. 4) is a littlelarger than the shoestring 2 width, so it allows the shoestring 2 tomove around at a small angle, which also facilitates the movement of thecrossing point of the shoestrings 2. Besides, the design also allows thefoot 3 to have some maneuvering space in the net of the shoestrings 2(as shown in FIG. 5). This allows more comfort for the foot 3 in thesleeper (as shown in FIG. 6).

Therefore, the user does not need to watch for the shoe head directionbefore putting feet 3 in the shoe body 1. The foot 3 can go into theshoe body 1 from either end and force the crossing point of theshoestrings 2 to move a little forward. The shoes finally look just liketraditional design to cover the feet. The shoes also provide the userwith required sturdiness and comfort.

In summary, the double head shoe structure in the invention does providea way to overcome the drawbacks for traditional sleeper design, so itdoes not need to watch for shoe head direction. It provides timesavingconvenience and certainly possesses progressiveness and commercialvalue.

1. A double head sleeper structure mainly comprises a shoe body and twocrossing shoestrings; the shoe body appears semicircular at both endsand a little concave in the middle of two sides; the size of shoe bodyvaries to meet different user's need; the characteristics are asfollows: the shoestring length is four fifth of the shoe body length;the two shoestrings cross with each other at the center of shoe surfaceof the shoe body; the two ends of the shoestring attach the two oppositesides of shoe body at a position two third of the shoe body length fromthe shoe end.
 2. As described in claim 1 for a double head sleeperstructure, the two ends of shoestring are directly clamped in a slotbetween shoe surface and shoe bottom.
 3. As described in claim 1 for adouble head sleeper structure, the two ends of shoestring are directlyclamped in a slot between shoe surface and shoe bottom, the said slotopening is a little wider than the string width, so it allows theshoestring to move around at a small angle, which also facilitates themovement of the crossing point of the shoestrings; besides, the designalso allows the foot to have some maneuvering space in the net of theshoestrings; this also allows more comfort for the foot in the sleeper.4. As described in claim 1 for a double head sleeper structure, the twoends of shoestring are directly inserted into a through hole from shoesurface to shoe bottom.
 5. As described in claim 1 for a double headsleeper structure, the two ends of shoestring are directly inserted intoa through hole from shoe surface to shoe bottom; the said through holeopening is a little wider than the string width, so it allows theshoestring to move around at a small angle, which also facilitates themovement of the crossing point of the shoestrings; besides, the designalso allows the foot to have some maneuvering space in the net of theshoestrings; this also allows more comfort for the foot in the sleeper.
